Managing unsolicited event invitations with user blocking

Managing unsolicited event invitations with user blocking in Google Calendar

You can now protect your calendar from repeated calendar spam and unwanted invitations. When you block a user in Google Calendar, the current event is automatically removed and you no longer receive new calendar invitations from that person.

In addition, when you block an individual in Calendar, they’re added to your account-wide blocklist, and interactions across all supported Google products are blocked. Similarly, if the individual was blocked in another supported Google product, their Calendar invitations will now also be blocked.

This feature allows blocking invitations from users with a Google account. To block invitations from a non-Google Calendar user, use the Gmail blocking functionality. This will block all emails from them, including emails that create Calendar events.

Google Calendar allows you to directly block spammers from event invites, automatically deleting the unwanted event and syncing the block across your entire Google Account. Launched in August 2026, this feature eliminates the manual cycle of deleting malicious or unsolicited invites. [1, 2, 3]

How to Block a User in Google Calendar

You can restrict a sender directly from the desktop or mobile interface using these steps: [4, 5]

Select the invite: Click or tap on the unwanted event in your Google Calendar.
Open options: Click the three-dot menu icon in the top right corner of the event card.
Block the user: Select the option to Block user.
Confirm: Verify the action in the pop-up prompt. [2]

Key Effects of User Blocking

Automatic Cleanup: The current event is instantly wiped from your view, alongside any recurring versions of it. [1, 2]
Cross-Product Syncing: Blocked individuals are added to your account-wide Google blocklist. This stops them from interacting with you across Gmail, Google Chat, and Google Meet. [1, 6, 7]
Bidirectional Integration: Anyone you have previously blocked in other Google apps will now be restricted from sending you Calendar invites as well. [1]
Zero Notifications: The blocked sender is not notified that they have been restricted. Their invitations fail silently on your end. [2]

Technical Limitations & Context Nuances

Scenario / Setup	Behavior & Actions Required
Non-Google Senders	The native Calendar block tool only targets Google account holders. For external platforms, you must use Gmail’s block function to stop the underlying emails from auto-generating events.
Delegated Accounts	If you manage someone else’s calendar, you cannot block users on their behalf. However, if a user you blocked sends an invite acting as a delegate for someone else, it remains blocked.
Secondary Calendars	You cannot block an organizer from a secondary calendar you subscribe to. To stop seeing those entries, you must unsubscribe from that specific secondary calendar.
Calendar Sharing	Blocking someone stops new invites but does not revoke pre-existing access if you previously shared your entire calendar layout with them. You must update your calendar’s sharing permissions manually.

Alternative Strategy: Changing Global Invitation Settings

If you want to stop unknown people from putting events on your schedule entirely without blocking them one by one, adjust your global settings: [8]

Click the Gear (Settings) Icon in the top-right corner of Google Calendar.
Choose Settings and look at the General tab on the left panel.
Click on Event settings.
Locate the dropdown menu for “Add invitations to my calendar”.
Switch it from From Everyone to “Only if the sender is known”. This restricts automatic event generation to people in your Google Contacts or those you have interacted with over email previously. [8, 9, 10]
